Road trains are the biggest road legal trucks around, hauling upto 3 trailers for a total overall length of 53.5 meters. Based on the large Kenworth's purpose built for these jobs, the cab has all the standard features. Bonneted prime mover, bullbar, large intakes and aerodynamic sleeper. The trailers are a 8 stud wide version of the 6 stud tanker I have previously created.
